About 1 Courtenay Close
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
1 Courtenay Close is a four-bedroom detached house in Old St. Mellons, Cardiff, Cardiff (CF3 5UL). It has a recorded floor area of 158 m² (around 1701 sq ft), construction records dating it to 1991-1995 and council tax band H. The latest certificate (April 2012) shows a D (score 63), on the cusp of jumping into the C band. Earlier certificates rated it C (March 2010); the latest reading is one band lower. Between certificates, roof efficiency dropped from Good to Average and hot-water efficiency dropped from Good to Average. The recommended improvements would push it to C (score 80).

Start your researchHow to read this page
Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 1 Courtenay Close is modelled from its 158 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in CF3 5UL. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
- Where sold prices come from
- Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 4 sales are recorded for 1 Courtenay Close. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 1 Courtenay Close was lodged in April 2012 at band D and expired in April 2022, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 1 Courtenay Close. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF3 5UL.
- Council tax band
- 1 Courtenay Close is in council tax band H. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
